Marv (n.): the ultimate insult. Someone who acts with no uniqueness in an annoyingly docile way, and shows an alarming amount of aggravating kindness. Their every action is predictable because they haven't had an original thought in their entire life. Nothing would be different if they didn't exist. This is reminiscent of an overly friendly neighbor so lame that you'd rather eat your own family than listen to them speak. Think Flanders from Simpsons. Always ducking out of having fun and being a wet blanket.

Dave- " Kaitlyn goes home every weekend and never comes out and drinks with us.
Steve- " oh my god she is such a marv"

Flea like creature living in or near the rectal area of a loved one. Marv's existence is known only by those closest to his host. Usually working in unison with TimmyMarv's existance is purely theoretical. Although Marv's outward appearance has yet to be documented his temperment is well known by all members of the 1128TH and most other soldier's serving in garrison with Minnie.

Outward manifestation of Marv's infestation can be charactorized by the severe mood swings of the host and often comical clawing and scratching of the infested area(s). In addition to Marv's ability to irritate his host while working in unison with Timmy he has been acredited with such hanus anus acts as causing Alabama Swamp Ass and the much dreaded Rusty Muffler. Leaving Timmy to bear much of the blame for these acts is yet another aspect of the cruel and sadistic nature of this specific species of ass passenger.
